Excel has them.
I've been speaking with a highly regarded boat builder about building me a custom 1860 modified vee aluminum boat. He no longer offers the grooved gunnels ( not sure of the correct terminology for this product ?) large quantities he has to purchase to get them. Personally , I can't imagine selling new boats without this option . He said if I would provide them , he would install them. Does anyone know where I can find this product ? Or a reputable custom builder that offers them on their boats ??
